Step 3

              Open the rear panel by lifting only the lower part
  • At first, there is a latch on the upper part, so only the lower part is lifted as much as it is lifted without force.
  • After lifting only as much as it can be lifted, pull it very slightly in the direction of the arrow in the photo, thinking that it is moving only 1mm very weakly. Very little!
